Ignition and Propagation Rates for Flames in a Fuel Mist

Abstract

The droplet size distribution in various experimental air-fuel sprays was measured using a holographic method. There was good agreement between upper-limit log-normal velocity distribution functions and the droplet size data. The Sauter mean diameter, maximum droplet diameter, and air-fuel ratio were also well represented by the data. Measurements of burning velocities in the sprays tested were compared with calculated predictions, and the results were satisfactory. Approximate burning velocities in modified fuel sprays produced under wind shear conditions were also calculated. (Author)
